I still don't have my main email account working and its now Friday, thats a week without email, I called tech support on Tues, Wed and Thu and been told by someone in India (that I couldn't understand half the time

) that they have done 'something' and it would be fixed in 24 hours.
I can now connect to my email account and check it for email but nobody can send me anything, everything thats been sent is coming back with '550 Invalid recipient.'
Am I the only one or are other people still having problems?
